Summary translation

Brassica juncea is an annual plant belonging to the Cruciferae family, used in our areas like green manure both for improving the organic matter, and for the soil biofumigation. There are some natural protection systems, based on the production of molecules with a biological activity against diseases and pest. In the family of Brassicaceae the chemical system Glucosinolates (GLS) – Myrosinase is present that is able to generate toxic compounds for pathogen fungi and nematodes. During the 2003 and 2004, the C.R.A.B. has tested the use opportunities of Brassica juncea as biofumigant. The action of the isothiocyanates present in B. juncea would appear performing also against the weed seeds of the soil. In the last years many scientists were interested to the capacity of some plant to absorb and to hyperaccumulate contaminant metals and radioactive elements. B. juncea was studied because is able to absorb selenium, sulphur, lead, chrome, copper, cadmium and zinc.
